COUNTER-OPERATING MECHANISM FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 455,123, dated June 30,1891.

Application filed February 18, 1891. gerial No. 381,853. (lilo model.)

To all whom it may concern:

Be it known that I, EDWARD CARSTENSIN DE SEGUNDO, a citizen of England,residing at No. 7 Victoria Street, WVestminster, in the cotlnty ofMiddlesex, England, have invented a new and useful Improvement inCounter- Operating Mechanism for Type-IVriters, of which the followingisa specification.

My invention relates to means for counting and registering the number ofwords printed by a type writer so as to determine the charges which areusually made at certain prices per folio of seventy-two words, or ofsome other number that may be determined on. As there are many differentconstructions of type-Writers, the apparatus for counting, according tomy invention, may have to be more or less modified as to the forms andproportions of its parts; but as all type-writers must have specialorgans for impressing a type, and also for advancing the line ofprinting for a blank space separating two words when no type is printed,I can, by mere modifications of form and position of the countingapparatus to suit different forms of type-writers, utilize these twodistinct movements for effecting the counting of words, as I shallexplain, referring to the accompanying drawing, Which is a front view ofthe motor part of apparatus applicable to a typewriter for counting thenumber of words printed.

A is a rod connected either directly or it may be through suitablebell-crank or other levers to a lever orbar moved downward when any oneof the types makes its impression, the connections being so arrangedthat for every impression the rod A is pulled downin the direction ofthe arrow. B is another rod similarly connected to that part of thetypewriter mechanism which advances the line of printing fora blankspace when no type is impressed, the rod B being by'that action pulleddown in the direction of the arrow. The rod A engages a pin on one arm Oof a bent lever pivoted by a pin 0 arranged in a hole which is slottedsufficiently to allow the rod A to make its upstroke without moving thelever-arm C. The other arm C of the lever carries a pawl D andterminates with a square angled end 0. The arm 0 is urged upward by aspring S. The rod Bis jointed to one arm E of a lever which is pivotedby a pin E and has on its other arm a stud E projecting under an arm E,which is mounted on the pin E, has a shoulder at c, and is urged down bya spring On the pivot-pin E is mounted a pawl D which, as well as thepawl D, engages with the teeth of a ratchetwheel IV. hen it is desiredto count by folios, each of seventy-two words, I make the ratchet-wheelIV with seventy-two teeth, or it might be with a simple fraction ormultiple of 72, and I gear this wheel to a counter of any known kind,showing by dials and indices or otherwise units, tens, hundreds, orother multiples of the revolutions of the wheel W. \Vhen the countingisby some donomination other than that of folios, the number of teeth ofIV and its gearing to the counter can be suited to the denominationadopted. Under the end of the arm F is mounted a cam G, which can beturned by hand to the position indicated by the dotted lines, so as toprevent the arm F from descending. The pivots C and E, the axis of camG, and the fixings of the ends of the springs S S are on a plate orframe H, of any convenient form, fixed in any convenient position on theframing of the type-writer and forming part of the casing of thecounter.

The action of the apparatus is as follows: When a letter is printed, therod A draws down the arm 0, advancing the arm (J and causing the pawl Dto advance the wheel \V one tooth; but by this movement of arm C its end0 comes in front of the shoulder e, and the arm I dropping holds arm Cin its advanced position, the arm 0 being thus held. down. Succeedingmovements of rod A in the printing of succeeding letters have then noeffect on arm 0 and produce no further movement of the wheel T; but whenafter all the letters constituting a word have been printed the rod 13is pulled down. Then arm F is raised, releasing the end 0 from theshoulder c, and arm 0 is raised by the spring S, ready to be pulled downwhen the first letter of the nextword is printed, so that the wheel \Vis again moved forward a tooth.

Thus, however, many letters occur in a word,

only one of them (the first) is registered on the counter, andhowever-many blank spaces the line of printing may be advanced there ICOis no registration. The pawl D prevents the wheel V from turningbackward.

In many cases when numerals are printed it is usual to reckon everynumeral as a word. hen this is to be done, the cam G is turned to thedotted position, preventing descent of arm F, consequently leaving thelevers C C in condition to move the wheel IV one tooth every time thered A descends.

In the apparatus above described the rods A and B are assumed to haveindependent movements, the rodAbeing pulled down only when a type isimpressed, and rod B being pulled down only when the line of printing isadvanced one space. As, however, the line must be advanced a space whena type is impressed, it may in some machines be difficult to secure thedesired independent movements of rods A and Bthat is to say, thedepression of rod B in moving the line one space may be accompanied bydepression of the red A.

In order to prevent the depression of the red A from registering when itaccompanies the depression of rod B, I link the pin on the arm E to apin on the pawl D, so that whenever rod B is depressed the pawl D islifted out of gear with the teeth of IV, and consequently the depressionof the rod A at the same time with red B effects no registration.

Having thus described the nature of my invention and the best means Iknow for carrying it out in practice, I claim- 1. A counter -operatingmechanism for type-writers, consisting of a rotating wheel forconnecting with a suitable counter, an

oscillating bent lever carrying at one end a pawl for engaging the wheeland provided at the opposite end with a rod adapted to be moved by apart of the type-writer when an impression is made, a pivoted leverhaving a rod adapted to be operated by a part of the spacing mechanismof the type-writer, a pivoted shouldered arm moved by and serving toengage the bent lever, and means for disengaging the arm from the bentlever when the aforesaid rod is moved by the spacing mechanism of thetype-writer, substantially as described.

2. The combination, in a counting mechanism for a type-writer, of aratchet-wheel IV, a bent lever having arms C C provided, respectively,with the red A and pawl D ,the pivoted lever E, having the rod B andstud E the pivoted shouldered arm F, adapted to engage and hold the bentlever, and a cam G for holding the shouldered arm out of engagement withthe bent lever, substantially as described.

I11 testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, this 6th day of February, A.D. 1891.
